本句为含宾语从句的复合句。这里主句谓语虽然用了过去时态，但宾语从句叙述的是客观事实，因此从句仍用一般现在时。再如：①The teacher told us (that) nothing is difficult if you put your heart into it. 老师告诉我们世上无难事只怕有心人。②She said (that) her father is twenty-eight years older than her. 她说她父亲比她大二十八岁。

    2. The store had a lot of different postcards, so it was hard to choose. 因为商店里有很多不同的贺卡，所以很难挑选。

    so 在这里为连词，意为“所以、因此”。本句也可说成：Because the store had a lot of different post cards, it was hard to choose.

    【注意】 “因为”和“所以”(because/so)，以及“虽然”和“但是”(though/but)，在汉语里是一起使用的，但英语中却不能同时使用，即“用了because不用so；用了but不用though”。如：①It was raining, so he didn't go out.= Because it was raining, he didn't go out. 天在下雨，所以他没出去。②Though he doesn't have much money, he lives happily. = He doesn't have much money, but he lives happily. 虽然他没钱，但他活得很幸福。

    3. I'm sure that she'll make new friends there! 我确信她会在那里结交新朋友。

    be sure＋从句。表示“某人对……有把握”。如：I'm sure that he is coming to help me. 我确信他会来帮我的。

    【拓展】 (1) be sure＋不定式。常用于祈使句，表示要求，意为“务必、请一定”。如：Be sure to telephone me and give me all the news. 务必给我打电话，告诉我所有的消息。

    (2) be sure＋of或about。意为“相信，对……有把握”。常用来表示某人主观上的看法。如：He is sure about this answer. 他相信这个答案。

    4. More and more flowbees were sold. 越来越多的flowbee被出售。

    more为much或many的比较级。more and more用在名词前，表示“越来越多的……”，如：There are more and more books in the library. 图书馆里有越来越多的书。

    【注意】 more and more用来修饰双音节或多音节的形容词或副词时，意为“越来越……”。如：English is becoming more and more important. 英语变得越来越重要了。

    5. The money was used to buy a car. 这些钱是来买小汽车的。

    be used to do sth. 意为“被用来做某事”。如：The wood was used to make a desk.这块木头是用来做桌子的。

    【注意】 be used to doing sth. 意为“习惯做某事”。如：Tom has used to eating Chinese food. 汤姆已经习惯吃中国食品。

    6. How about you? 你呢？

    How about... 是英语口语中常用的省略句型，意为“……怎么样？”，后面可以跟名词、代词或动名词，常用于向对方提出建议或请求、征询对方的看法或意见。如：How about going out for a walk? 出去散散步好吗？
